Hi,
I cannot help you with the wrong behaviour, but the warnings are all
correct but can probably safely be ignored.

Declaring "void;" is not too useful. Probably the whole lines should be
commented (not only the remaining prototype tokens).

All of these are true if the if-block in 171--173 is (always) used.
The static condition statically evaluates to true. But I admit that one
warning per unreachable code block would suffice ...

Code following a while (1) {} *is* unreachable. Correct again.

Again: "void;" *is* useless.

This is correct: These lines are skipped due to the preceeding goto.

"void;" ...
